FEA Results Interpretation for a Pin Support

  1. Sep 23, 2016 #1
    Greetings to all,

    I am doing FEA analysis of a jib crane. I am using Autodesk Inventor.

    The results show that the max Von Mises stress in the support pin is 773 MPa. This value exceeds the yield strength of the Carbon Steel. Does this mean that the Pin will fail under load ?

    It could mean that, but you need to do a careful analysis of your boundary conditions, mesh density, and potential geometry issues that might be causing an artificially high result.

    What does your mesh density look like on the pin, and what boundary conditions are you using to support it in the plate?
